Client stops with error message

Running 9.0.1 full client in Windows 7/64

recently, the client sometimes will not start. The startup log has an entry for DESK_CHECKNOTES2ALIVE_TIMER.

When I run a nfixup manually, the client starts.

My hypothesis is that Notes encounters a problem, excutes a fixup, which then takes too long and the timer kills the client.

Is there any way to extend the cutoff, give the client more time to start?

Kind regards,

Lars
